We selected 43 patients who had signs and symptoms of delayed hydrops and analyzed their clinical features statistically. The diagnosis had been made during the past 10 years. The most common type of hearing loss was juvenile unilateral hearing loss of unknown etiology. The interval between the onset of hearing loss and the start of vertigo was as long as 10 years or more. In patients whose symptoms were due to mumps or sudden deafness, the. latent period was generally within 20 years.
